Everyone is quite right about the adjustable power supply suggestion. I was fixated on the power supply issue without considering the nature of the load.
I like Walt's suggestion of simply switching in more LEDs as needed. A rotary switch adding more LEDs with each position would make adjusting the light level easy with a simple turn of the knob. It may be "brute force" as Walt says, but sometimes the simplest is also the most elegant and efficient solution. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Walter Underwood Sent: Saturday, January 7, 2017 8:08 AM To: Elecraft Reflector Subject: Re: [Elecraft] Dimmable LED desk lamp for operating position recommendation needed A brute force solution would be to get four LED lighting strips that run off 12V and use four switches. Turn on as much light as you want. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
